Rosacea

Rosacea is a chronic (long-lasting) inflammatory condition that mainly affects the center of the face — the cheeks, nose, chin, and forehead. The main sign is redness that does not fully go away. Some people also flush easily, get small visible blood vessels, or develop red bumps and pus-filled pimples that look like acne.

Rosacea tends to come and go. People have flare-ups followed by calmer periods. Triggers like sun, heat, alcohol, or stress can set off a flare. Over time, and without treatment, symptoms can slowly get worse.

It is harmless in the sense that it will not spread to others, but it can affect how the skin looks and feels. The good news is that today's treatments can control it well for most people.

Rosacea almost always includes at least one main sign:

• Flushing: Sudden redness that comes and goes. Often the earliest sign.
• Persistent redness: Redness in the center of the face that stays.
• Bumps and pimples: Unlike acne, rosacea does not cause blackheads.
• Visible blood vessels: Thin red lines (telangiectasia).
• Stinging or burning: Skin may sting, itch, or feel tight.
• Thickened skin: Sometimes on the nose (rhinophyma).
• Eye symptoms: Dry, gritty, red eyes; ocular rosacea affects more than half of people with rosacea.

In brown and Black skin, redness can be harder to see; watch for swelling, warmth, dryness, or burning.

Newer thinking (the phenotype approach) looks at which features a person actually has:

• Redness and visible vessels (erythematotelangiectatic).
• Bumps and pimples (papulopustular).
• Thickened skin (phymatous), usually on the nose.
• Eye involvement (ocular).

Most people have a mix, and treatment is chosen based on which features are present.

The exact cause is not fully known. Experts believe several things work together:

• Genetics: Often runs in families.
• An overactive immune system: A protein called cathelicidin builds up and drives inflammation.
• Blood vessels and nerves: Facial nerves and vessels are extra sensitive.
• Demodex mites: People with rosacea have far more of these tiny mites.
• Skin barrier problems: The barrier is often weaker.

Rosacea is not caused by poor hygiene and is not an autoimmune disease.

Triggers can set off or worsen a flare. Common ones include:

• Sun exposure (the most common)
• Hot or cold weather and wind
• Hot drinks, spicy foods, and alcohol (especially red wine)
• Hot baths, showers, and saunas; overheating
• Exercise
• Emotional stress
• Harsh skincare (alcohol, fragrance, menthol, exfoliants)

There is no lab test for rosacea. A doctor diagnoses it by examining your skin and asking about symptoms and triggers. They may rule out look-alikes such as lupus, seborrheic dermatitis, or acne. If your eyes are involved, you may be referred to an eye doctor.

Gentle daily skin care is the foundation and can noticeably reduce redness:

• Cleanse gently with a mild, fragrance-free cleanser and lukewarm water.
• Moisturize to repair the barrier.
• Wear sunscreen every day — broad-spectrum mineral SPF 30+.
• Cool it down with a cool, damp cloth during a flare.
• Skip irritants — alcohol, fragrance, menthol, acids, scrubs. Never use OTC steroid creams.
• Avoid your triggers.

Rosacea skin is sensitive skin, so the goal is calm and gentle. Look for fragrance-free products for sensitive skin: a mild non-soap cleanser, a barrier-repairing moisturizer, and a daily mineral sunscreen. Ingredients with some evidence for redness or bumps include azelaic acid and niacinamide. Avoid alcohol, fragrance, menthol, witch hazel, and scrubs. This is general guidance, not a product endorsement.

Most people need prescription treatment. Combinations are common:

• Metronidazole (cream/gel).
• Azelaic acid (gel/foam).
• Ivermectin cream (Soolantra).
• Brimonidine / oxymetazoline to temporarily reduce redness.
• Low-dose doxycycline (Oracea, 40 mg) for its anti-inflammatory effect.
• Isotretinoin for severe or stubborn cases (not in pregnancy).

For lasting redness and visible blood vessels that creams cannot fix, in-office light treatments often work better. Lasers (such as pulsed-dye laser) and intense pulsed light (IPL) reduce the small vessels behind facial redness over a few sessions. For rhinophyma, laser or surgical reshaping can help.

See a dermatologist if OTC care is not helping or symptoms worsen; you have bumps or fixed redness; your nose looks enlarged; you have eye symptoms (ocular rosacea can rarely threaten vision); or rosacea affects your confidence. Early treatment works better.

• Acne: Has blackheads and whiteheads, which rosacea does not.
• Seborrheic dermatitis: Red, flaky, greasy patches; scaling is the giveaway.
• Lupus: A butterfly rash that flares in sun; often scaly and affects the whole body.
• Steroid-induced rosacea: Caused by steroid creams on the face.
• Perioral dermatitis: Small bumps around the mouth or eyes.
